Just a quick comparison of the camera between the fun HTC Re and the iPhone 6S Plus. 

The shots are taken minutes apart. 

With the HTC Re you have no viewfinder. It’s video, slow motion, time lapse and stills all without a viewfinder. You can also live broadcast to YouTube. My full review will cover more. 

The shot below is from the HTC Re. 

  
This is 12mp at 16:9. It can shoot 16mp at 4:3. 

And now the iPhone 6S Plus. 

  
Which do you prefer? Note there was some mist/fog.
